Cantilever racks are shelving systems without front uprights, in which horizontal arms are attached to a column on one or both sides, allowing long goods and bulky items to be stored openly and accessibly.
Key facts
- Cantilever racks have no front upright, allowing long goods and bulky items to be stored without any length restriction.
- They are available in single-sided and double-sided configurations and suitable for both indoor and outdoor use, with outdoor versions typically being hot-dip galvanized.
- Load capacity, arm spacing and handling equipment must be coordinated during planning to ensure safe and efficient processes.
- Fixed cantilever racks are subject to a regular visual inspection requirement, particularly for impact damage and deformation to columns and arms.
- Mobile cantilever racks on castors enable flexible warehouse layouts but require special attention to stability and locking during operation.
What are cantilever racks?
Cantilever racks are storage systems in which horizontal load arms – known as cantilever arms – are attached laterally to vertical columns, without a front upright limiting the storage area. This creates a continuously open loading side suited to goods of considerable length or irregular shape: pipes, profiles, timber beams, sheet metal, ladders and mattresses can be stored without interruption and without complex repacking processes. The design allows direct handling by forklift, crane or loader crane, depending on the equipment and operating conditions.
Designs and configurations
Cantilever racks are available in single-sided and double-sided configurations. Single-sided variants are typically installed against walls and make efficient use of available space. Double-sided systems are freestanding and can be loaded from both sides. For outdoor use, columns and arms are frequently hot-dip galvanized or coated with corrosion-resistant finishes. Common accessories include anti-roll stops and locking pins to prevent stored goods from sliding off, grid panels or wooden planks as support surfaces, roofing for open-air storage and impact protection profiles at the column base. In addition, mobile cantilever racks on castors are available, suitable for changing production locations or seasonal storage requirements. Whether stationary or mobile, indoor or outdoor – the decision depends on the product portfolio, the available handling equipment, and the space and weather conditions.
Practical considerations and selection criteria
The following aspects should be considered during warehouse planning:
- Load capacity per arm and per column: Manufacturer specifications apply to evenly distributed loads; point loads or one-sided loads can significantly reduce permissible values.
- Arm spacing and length: Both dimensions are determined by the length and weight of the stored goods as well as the number of support points required for safe storage.
- Rack inspection requirements: Like other fixed racking systems, cantilever racks are subject to regular inspection for damage caused by impacts or overloading; DGUV recommendations and EN 15635 provide guidance, although the specific inspection practice is governed at the operational level.
- Handling equipment: The choice between forklift, telescopic fork, crane or manual storage affects the required aisle height, aisle width requirements and the structural design of the arms.
- Corrosion protection: For outdoor storage or humid production environments, surface treatment is a quality feature that noticeably affects maintenance intervals and service life.
A cantilever rack is not a substitute for a complete long goods storage concept. When large quantities or very heavy profiles are being moved, crane runways, long goods conveyors or automated long goods storage systems are frequently added as complements. The cantilever rack then forms only one part of the overall system.
